Introduction
Welcome to the FiiO JT7 Over-Ear Planar Magnetic Headphones user manual. This guide provides essential information for setting up, operating, maintaining, and troubleshooting your new headphones. Please read this manual thoroughly to ensure optimal performance and longevity of your device.
The FiiO JT7 headphones are engineered for audiophiles, featuring advanced planar magnetic drivers and a comfortable, lightweight design for an immersive listening experience.
Product Overview
The FiiO JT7 headphones incorporate several key features designed to deliver high-fidelity audio and superior comfort:
- 95x86mm Planar Magnetic Driver: Equipped with FiiO’s self-developed planar magnetic driver, the JT7 delivers a wide soundstage and powerful bass. Every component, from the magnetic circuit to the diaphragm, is independently developed by FiiO to ensure professional-grade sonic performance and long-term stability.
- 3µm Ultra-Thin Diaphragm: For quick vibration and sensitive response, the JT7's diaphragm measures just 3µm, enabling it to precisely capture minute changes in the electrical signal. This results in excellent transient response performance and brilliantly clear treble.
- F.E.S. Elastic Support System: FiiO’s exclusive F.E.S. (FiiO Elastic System) enhances diaphragm elasticity through a special textured design, increasing vibration amplitude for deeper, more dynamic, and flexible bass.
- Dual-Sided High-Density Magnet Array: The dual-sided N52 neodymium magnetic array provides strong magnetic force, achieving a high sensitivity of 92dB/mW. This allows the JT7 to be easily driven by portable devices while still producing full, energetic sound.
- Ultra-Light 318g Foldable Design: Weighing only 318g, the JT7 is significantly lighter than many planar headphones. The four-axis ergonomic design ensures a comfortable fit for long listening sessions, and it folds compactly for easy storage and travel.
- Replaceable Earpads & Headband: The breathable mesh fabric earpads reduce heat build-up during extended wear. Both the earpads and headband are detachable for easy cleaning and replacement.
- Detachable Cable System: Includes both a 3.5mm to dual 3.5mm single-ended cable and a 4.4mm to dual 3.5mm balanced cable, plus a 6.35mm adapter, ensuring compatibility with various audio sources.

Setup
- Attach the Audio Cable: Select the desired audio cable (3.5mm single-ended or 4.4mm balanced). Connect the dual 3.5mm ends firmly into the headphone earcups, ensuring a secure connection.
- Connect to Audio Source: Plug the other end of the cable into your audio source (e.g., smartphone, DAP, amplifier). If your source requires a 6.35mm connection, use the included adapter.
- Adjust Headband: Place the headphones on your head. Adjust the headband sliders on both sides until the earcups comfortably cover your ears and the headband rests gently on your head. The four-axis ergonomic design allows for precise fit adjustments.
- Position Earpads: Ensure the earpads fully enclose your ears without excessive pressure. The breathable mesh fabric earpads are designed for comfort during extended listening.

Operating Instructions
- Power On/Off Audio Source: Ensure your audio source is powered on and playing music.
- Volume Control: Adjust the volume using the controls on your connected audio source. Start with a low volume and gradually increase it to a comfortable listening level.
- Optimal Listening: For the best audio experience, ensure the headphones are properly seated on your head, and the earcups form a good seal around your ears.
- Compatibility: The FiiO JT7 headphones are compatible with a wide range of devices including laptops, desktops, cellphones, tablets, gaming consoles, and televisions, provided they have a compatible 3.5mm or 4.4mm audio output.

Maintenance
- Cleaning: Use a soft, dry cloth to wipe the headphones. For earpads and headband, a slightly damp cloth can be used, but ensure they are completely dry before use. Do not use harsh chemicals or abrasive materials.
- Earpad and Headband Replacement: The earpads and headband cushion are detachable for easy cleaning and replacement. Gently pull to remove and align to reattach. Replacement parts can be purchased from authorized FiiO retailers.
- Cable Care: Avoid sharp bends or excessive pulling on the audio cables. Store cables neatly when not in use to prevent tangling and damage.
- Storage: When not in use, store the headphones in a cool, dry place, away from direct sunlight and extreme temperatures. The foldable design allows for compact storage.

Troubleshooting
- No Sound:
- Ensure the audio cable is securely connected to both the headphones and the audio source.
- Check the volume level on your audio source and ensure it is not muted.
- Test with a different audio source or cable to rule out component issues.
- Poor Sound Quality (Distortion, Low Volume):
- Verify that the audio cable is fully inserted into all jacks.
- Ensure your audio source is capable of driving high-impedance headphones (if applicable). The JT7 has a sensitivity of 92dB/mW, making it relatively easy to drive, but a dedicated amplifier can enhance performance.
- Check the audio file quality. Low-quality audio files may sound poor even on high-fidelity headphones.
- Uncomfortable Fit:
- Adjust the headband sliders and earcup rotation to find the most comfortable position.
- Ensure the earpads are not twisted or improperly seated.
